=CHAPTER Intro
B<Pod> is an evolution of Perl 5's L<I<Plain Ol' Documentation>|doc:perlpod>
(POD) markup. Compared to Perl 5 POD, Perldoc's Pod dialect is much more
uniform, somewhat more compact, and considerably more expressive. The
Pod dialect also differs in that it is a purely descriptive mark-up
notation, with no presentational components.
